Definitions

  • the present invention relates to cap seals and the like used ordinarily for the sealing of bottles and the like and it concerns more particularly the cap seals intended to cover the necks of bottles previously sealed by means of any suitable means.
  • the cap seals of the present invention are placed as a capsule over the neck and mouth of a bottle and are generally constructed either by metallized papers suitably glued on the neck of the bottle or by sheathing of thermoplastic material or the like.
  • thermoplastic material in order to render inviolable the said capsule thus constructed, one had to heat said sheathing of plastic material so that said sheathing may take the exact shape of the contour of the neck of the considered bottle and that said sheathing may adapt itself on either side of the flange generally present in the vicinity of the upper end of the bottle.
  • This subjection is very awkward in practice and slows down considerably the operation of placing a capsule on the bottle when it has to be made in a standardized production on a large number of bottles previously sealed.
  • Besides the heating of said capsules necessitates, for their simultaneous adaptation on the considered bottles, machines and apparatus which are very expensive and complicated.
  • the present invention aims more particularly toward the manufacture of capsules which are to be put on a bottle, allowing thus a quick and easy adaptation on the bottles without necessitating either any special tool or any prior heating.
  • the capsule to be placed on a .bottle according to the invention is absolutely inviolable 45 and thus warrants the authenticity of the contents of the considered bottle.
  • the manufacturing of said capsule by molding of a suitable plastic material allows the advantageous combination of said cap seals with the different methods and known devices for effective sealing.
  • the cap seal according to the invention is manufactured by molding of a plastic material such as for instance polyethylene, polyvinyl chloride or some polyamides so that this material can be stretched elastically outof shape, and said cap seal is pricipally noteworthy "in that its body is of a general cylindrical shape and comprises for the housing of the flange of the bottles neck or the like an annular recess, the lower wall of which formsa stop abutting against the corresponding horizontal shoulder, of the flange and prevents thus any removal of said cap seal after it has been set in place, the diamthe bottles neck or the like, the skirt of the body (that is to say the part located below the annular recess for top to the bottom, the lower edge of said skirt being of a trifling thickness so that it may easily stretch out of 2,947,432 Patented Aug. 2, 1961] ice shape during the driving and then may contract itself when in place in order to fit narrowly the shape of the bottles neck.
  • a plastic material such as for instance polyethylene, polyvinyl chloride or
  • the skirt of the cap seal comprises inner vertical projecting parts which have the shape of wedges and which contain between them passages for the escape of the air enclosed inside the cap seals by the setting in place thereof on the neck.
  • said vertical projecting parts may extend themselves over the whole length of said skirt or may be made in a fragmentary manner by constituting thus horizontal rows of suitable reliefs.
  • the upper end of said projecting parts which corresponds to the greater thickness of the wedgeshaped profile constitutes the discontinuous lower wall of the annular recess and fits under the lower shoulder of the flange of the bottles neck.
  • the cap seal to be utilized as a capsule on a bottles neck according to the invention may be combined with dilferent sealing means of the bottle iself, its easy setting in place on the bottles neck and its adherence on the flange of said neck thereby obtaining a perfect seal. Furthermore it goes without saying that manufacturing the capsule in a molded plastic material facilitates considerably the following combinations: the assembly constituted 'by the cap seal to be utilized as a capsule on a bottles neck, and the sealing means manufactured in only one suitable molding operation.
  • Fig. 1 is a vertical section of a cap seal to be put on a bottles neck according to the invention.
  • Figure 2 is a partial vertical section of the neclcof a bottle on which said cap seal is to be mounted.
  • Fig. 3 shows a vertical section of the cap seal and of the' bottles neck during the initial stages of applying said cap seal on said bottles neck.
  • Fig. 4 shows the neck of the bottle covered with the cap seal according to the invention.
  • Fig. 5 is a vertical section at a greater scale of a cap seal manufactured according to an embodiment of the invention.
  • Fig. 6 is a horizontal section along line VI- VI (Fig. 5).
  • Fig. 7 shows a partial vertical section of the wall of a cap seal according to another embodiment of the invention.
  • Fig. 8 shows a section of a further embodiment of manufacture of the cap seal according tothe invention.
  • Figs. 9, l0 and 11 represent some examples of manufacture of cap seals to be placed as a capsule over the bottles neck according to the invention combined with sealing obturator devices.
  • Fig. 12 shows a variation of the cap seal of Fig. l.
  • the cap seal intended to be placed as a capsule on a bottles neck and illustrated in Fig. 1 is formed by molding a supple plastic material for instance colored or uncolored polyethylene according to the decorative aims which should be reached.
  • the skirt of the cap seal may comprise any desired motive or any desired publicity.
  • Said cap seal presents the shape of a hollow cylindrical body sealed at its upper extremity and open at its lower extremity.
  • the body of the cap seal comprises a cylindrical part having an inner diameter A equal (or preferably very slightly less) to the external diameter A of the upper extremity of the bottles neck of Fig. 2.
  • the body of the cap seal com prises a marked shoulder defining a lower skirt the outside of which is nearly cylindrical but the thickness of the wall of which varies according to each place. Starting from the top one meets first an'inner annular recess of a diameter -B equal (or preferably slightly less.) to the outside diameter B of the flange of-the bottles neck.
  • the materials thickness of the skirt is increasing from the bottom, starting from the diameter D and ending at the diameter C, the thickness at the level of the diameter C being maximum and delining a real step intended to fit under the lower horizontal shoulder of the flange of the neck. Said step avoids any voluntary or untimed withdrawal of the cap seal which when once adapted on the neck may never be removed without tearing.
  • the setting in place of the cap seal is however easy and quick owing to the deformability of the plastic material constituting the body of the cap seal. 'As one may see in Fig. 3, the lower skirt is easily stretched out of shape in order to allow passage for the flange of the neck which, once placed in the annular recess, is tightly locked within said'capsule. If the inner diameters of the different parts of the capsule are made slightly smaller than the outside diameter of the corresponding parts of the neck, the cap seal is held perfectly place without needing any previous heating. It may be thus driven in place 'simply'with the hand or with the help of any appropriate instrument or tool.
  • the placing in place of the plastic cap seals of the present in- "vention necessitates no setting or the like as is the case with the cap seals of metallizedpaper or of a sheet of metal.
  • the step of the cap seals skirt is not made continuously along the inner periphery of said skirt but it is constituted by the upper extremity of vertical projecting parts a of a decreasing thickness from the top to the bottom.
  • this form of manuiiacture procures identical advantages to those of the cap seal of Fig. 1 as well as decreasing substantially the weight of the body of said cap seal and also in leaving 'freespaces between the projecting parts for the escape of the airenclosed in the cap seal when it is driven in place.
  • the vertical projecting parts may be alsocut out horizontally so as to form peripheral rows of varying thickness of reliefs.
  • Fig. 8 is shown the application of the invention to a'known type of cap seal for the sealing of a bottle or for the placing as a capsule on a bottles neck.
  • the cylindrical skirt comprises a series of circular horizontal flanges c intended to bear against the neck in order to form a labyrinth joint.
  • a cap seal for placing over the bottles neck is represented by f, and the horizontal upper bottom of which comprisesa vertical cylindrical projecting part represented by g is intended to be engaged in the inner part of the :bott'les neck, that is, the circular edge of the neck is placed betweensaid projecting part g and the inner wall of the cap seal 1.
  • the sealing and placing of the cap seal on the bottles neck may be then manufactured in a single operation and with the help of a single cap seal which is easily manufactured by molding.
  • the upper bottom of the cap seal f comprises, on the one hand, a circular projecting part It having annular ribs and, on the other hand, a hollow i for the opening of a bottle or flask with the help of a corkscrewor the like.
  • the cap seal may present itself from the outside under the form of a cylindrical body such as that shown schematically on Fig. 12.
  • the outside cylindrical wall comprised between the upper horizontal bottom and the lower extremity of the skirt, is rectilinear anddoes not comprise the unliooking of Fig. 1, for the housing of the neck flange. This setting may eventually simplify the molding of the cap seal in avoiding the necessity to obviate a corresponding projecting part in the mold.
  • a plastic cap seal for the sealing of containers having a neck and an annular flange on said neck
  • said plastic cap seal comprising an'upper part having a recess for the annular flange of the neck of the container, a skirt, -anannular shoulder in the inner surface of the skirt definingthe lower 'margin of said recess for the annular flange of the neck, the thickness of said skirt decreasing progressively from said shoulder to its lower extremity, and means on the inner surface of said skirt enabling the air enclosed in said cap seal to escape when driven in, said skirt ending in a flexible and elastically deformable circular edge the diameter of which is slightly less than the diameter of said neck to effect a snug fit, the elasticity of said skirt causing the engagement of said shoulder under said flange of said container neck to prevent any removal of said cap sea-l when .once set in place.
